Phonocardiography is the graphic registration of various bands of the vibratory spectrum. We used the phonocardiogram as a monitoring apparatus. A 62-year-old man was scheduled for mitral valve replacement. After induction of general anesthesia and tracheal intubation, we inserted an esophageal stethoscope attached with a wireless microphone, amplifier, galvanometer and transcription system. The resulting phonocardiogram revealed a pan-systolic murmur. After successful replacement of the mitral valve, the phonocardiogram showed no sign of heart murmur. So we are convinced that the application of the phonocardiogram can be a useful monitoring device for valvular surgery.

흉추 경막외 차단법과 Esmolol 에 의한 유도 저혈압 마취후 술후 간기능검사의 비교
강정권,연준흠,홍기혁,한송욱 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.34 No.3
Background: Induced hypotension reduces blood loss in the surgical field and provies better visibility. May methods have been used for induced hypotension. Recently Esmolol is favored in induced hypotension because of its short action of sympathetic beta-1 receptor antagonist and easy to control. Thoracic epidural block can provide cadiovascular stability in induced hypotension. The purpose of the study is to compare postoperative liver function after induced hypotension between thoracic epidural blockade and esmolol combined with general anesthesia with isoflulane. Method : Fourty patients scheduled for spinal posterior fusion under general anesthesia were randomly divided into two groups. In thoracic epidural blockade group(Group I, 20 patients), 8∼10 ml of 2% lidocaine was injected into the epidural catheter located in T6∼7 interspace in a bolus. In Esmolol group(Group II, 20 patients) received 0.5 mg/kg as loading dose and 50∼150 g/kg/min continuously. We measured preoperative and postoperative 1, 3, 7 day's serum glutamic-oxaloacetic transaminase(SGOT), serum glutamic-pyruvate transaminase(SGPT) and alkaline phosphatase(ALP). Result : In the thoracic epidural blockade group, there was statistically significant increase of SGOT level above normal range on postoperative 1 day, which decreased on postoperative 3 and 5 day(p<0.05). But it was within normal range on postoperative 7 day. SGPT was increased within normal range. Similarly, in the esmolol group, there was statistically significant increase of SGOT level above normal range on postoperative 1 day, which decreased on postoperative 3 and 5 day(p<0.05). But it was within normal range on postoperative 7 day. SGPT was increased within normal range. The level of ALP was increased within normal range in both groups. There was no statistically significant difference in liver function between two groups. Conclusion : We consider that postoperative liver function is little influenced with induced hypotension by thoracic epidural blockade and esmolol combin with general anesthesia with isoflurane.

흉부 경막외 차단과 Esmolol 을 이용한 유도 저혈압 마취의 비교
김정원,연준흠,홍기혁,한송욱 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.34 No.4
Background : Induced hypotension reduces blood loss in the surgical field and provides better visibility. For induced hypotension, many methods have been used. Recently esmolol is favored in induced hypotension because of its short action and easy controlability, but thoracic epidural block is seldom used in induced hypotension. So we compared the effect of esmolol and thoracic epidural block in induced hypotension. Method : Patients scheduled for spinal posterior fusion under general anesthesia were randomly divided into two groups. In thoracic epidural group(Group I, 20 patients), 8∼10 ml of 2% lidocaine was injected into the epidural catheter located in T6-7 interspace in a bolus. In esmolol group (Group II, 20 patients), 0.5 mg/kg of esmolol received as loading dose and 50∼150 g/kg/min infused continuously. We measured mean arterial pressure, central venous pressure, heart rate, amounts of administrated fluids, urine output and VAS score. Result : There were no statistically significant differences beten the two groups in amounts of bleeding, administered fluid, urine output. The elapsed time to reach the state of induced hypotension(MAP 55∼65 mmHg) is 15.1 2.4 min after lidocaine injection in Group I and 6.1 2.7 min after esmolol injection in Group II(p<0.05). There were statistically significant differences between two groups in mean arterial pressure in 10 min after the injection(p<0.05). But there was apparent difference in VAS score in postoperative 1 hrs, 2 hrs and 6 hrs(p<0.05). Conclusion : Thoracic epidural block is another method for induced hypotension. And postoperative pain control can be easily achieved by injection through epidural catheter. (Korean J Anesthesiol 1998; 34: 827∼831)
